Abstract
This utility model relates to a kind of Medical C-arm Motorized lift device, comprise metal outer cylinder and metal inner core, described metal inner tube installation is in metal outer cylinder, and in metal inner core, electric pushrod is installed, between metal outer cylinder and metal inner core, polymer material layer is installed, described polymer material layer is that polytetrafluoroethylmaterial material is made, in order to the gap between filler metal urceolus and metal inner core.This utility model is simple and reliable for structure and cost is low, workable, can well be applied in Medical C-arm structure, solves the problem that traditional structure is complicated, service life is short; Utilize the gap between politef filler metal inner core and metal outer cylinder, mainly play lubrication and wear-resisting effect, ensure between two metal cylinder without rubbing and can using the long-life.
Description
Technical field
This utility model relates to technical field of medical equipment, specifically refers to a kind of lowering or hoisting gear, particularly relates to a kind of Medical C-arm Motorized lift device.
Background technology
Medical C-arm apparatus lifting device is this equipment in use Application comparison device frequently, in order to head it off, the key of the design is to introduce a kind of novel high polymer material (politef), between two rubbing surfaces this material being filled in Medical C-arm apparatus lifting device, therefore material has hardness high (comparatively metal is low), good springiness, high temperature resistant and coefficient of friction is extremely low, there is fabulous lubrication, the features such as wear-resisting effect, achieve between two friction areas completely isolated, without wearing and tearing, undeformed, make this update device fault-free in whole life cycle.
Medical C-arm equipment is mainly used in hospital operating room, when performing the operation, this kind of equipment is needed to position and judgement to surgical effect, once this C-arm device fails will cause operation to be difficult to carry out or carry out, so this device reliability of needing to ensure that it is absolute and stability.
The service life of general medical equipment is the longest will reach 10 years, and conventional apparatus once calculates by using every day, use the situation that will there will be gap and obviously increase after a year, will reach 50% at the probability of use these parts damages after 3 years.Current most domestic producer all adopts the mode of installing ball bearing between metal cylinder to realize its elevating function, hardness ratio two metal cylinder of ball bearing is all hard, long-term elevating movement can cause metal to produce wearing and tearing, gap between metal cylinder will be caused after wearing and tearing to increase, gap is large and will cause ball bearing unbalance stress, cause ball bearing damage the most at last, ball bearing damage will cause equipment normally not carry out the work, change ball bearing is again a more loaded down with trivial details thing simultaneously, medical equipment entirety need be dismantled could change it completely, therefore its service life is short, fault rate is high, maintenance process is loaded down with trivial details, maintenance cost is high.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides a kind of Medical C-arm Motorized lift device, by being provided with polytetrafluoroethylmaterial material layer between metal inner core and metal outer cylinder, utilize this material hardness high (slightly lower than metal hardness), skin-friction coefficient low, lubricate the inherent character such as good to replace traditional bearing, guarantee the operation that Medical C-arm equipment can be reliable and stable, improve stability and the reliability of Medical C-arm equipment.
This utility model is achieved through the following technical solutions:
A kind of Medical C-arm Motorized lift device, comprise metal outer cylinder and metal inner core, described metal inner tube installation is in metal outer cylinder, and in metal inner core, electric pushrod is installed, between metal outer cylinder and metal inner core, polymer material layer is installed, described polymer material layer is that polytetrafluoroethylmaterial material is made, in order to the gap between filler metal urceolus and metal inner core.
As optimal technical scheme of the present utility model, the thickness of described polymer material layer equals the thickness in gap between metal outer cylinder and metal inner core.
Compared with prior art, the beneficial effects of the utility model are: this utility model is simple and reliable for structure and cost is low, workable, can well be applied in Medical C-arm structure, solve the problem that traditional structure is complicated, service life is short; Utilize the gap between politef filler metal inner core and metal outer cylinder, mainly play lubrication and wear-resisting effect, ensure between two metal cylinder without rubbing and can using the long-life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-metal outer cylinder; 2-metal inner core; 3-electric pushrod; 4-polymer material layer.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of Medical C-arm Motorized lift device, comprise metal outer cylinder 1 and metal inner core 2, described metal inner core 2 is arranged in metal outer cylinder 1, and in metal inner core 2, electric pushrod 3 is installed, by loading onto electric pushrod 3 in the inside of metal inner core 1, this device electric up-down function can be realized.
Between described metal outer cylinder 1 and metal inner core 2, polymer material layer 4 is installed, described polymer material layer 4 is made for polytetrafluoroethylmaterial material, in order to the gap between filler metal urceolus 1 and metal inner core 2, in the present embodiment: the thickness of described polymer material layer 4 equals the thickness in gap between metal outer cylinder 1 and metal inner core 2.By utilizing politef (a kind of macromolecular material, politef another name Teflon, there is high, the resistant to elevated temperatures feature of hardness, coefficient of friction is extremely low, have fabulous lubrication, wear-resisting effect) gap between filler metal inner core and metal outer cylinder, mainly play lubrication and wear-resisting effect, ensure between two metal cylinder without rubbing and can using the long-life.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
